Other types of connections, for example, welding or soldering are not recommended by EURO-
CLIMA, because of risk of fire to neighboring materials. If one of those types of connections are
chosen, the assembler is fully responsible for this task and associated hazards.
The piping for the heat exchanger should not hinder any maintenance required.
The connection of the heat exchanger is to execute as stipulated on the label on the AHU (connec-
tion diagrams in

Heat exchanger connection
The heat exchanger operates according to the cross-counter-flow principle. Only a preheat ex-
changer can be supplied for parallel flow operation on request by the customer.
1. All standard heating and cooling heat exchangers - counter flow
2. Steam heat exchangers: steam inlet top, condensate bottom - counter flow
3. A Preheat exchanger is needed if there is a freezing risk and can be requested.
